RUBBER-TIRE SETTER.

SPECIFICATION forming part of Letters Patent No. 662,686, dated November 2'7, 1906.

Application filed May 26, 1899. Serial No. 718,455. (No model.)

To (tZZ whom it may concern.-

Be itknown that I, SAMUEL W. COLLINS, a citizen of the United States, residing at In dianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Rubber-Tire Machin'es, of which the following is a specification.

My invention relates to improvements in rubber-tire machines.

It especially relates to machines for securing onto vehicle-wheels rubber tires, which are held in place byaretaining band or hands of metal extending through the ru bber of the tires.

My invention consists in the constructions and combinations of parts hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a front elevation of amachine embodying my invention. Fig. 2 is a side elevation, some of the parts being broken away. is a detail View of the clamping-jaws, partly in section. with the top jaw removed. Fig. 5 is a side elevation of the wheel-clamp. Figs. 6 and 7 are detail views of the wheel-support. Fig. 8 is an elevation showing the position of the parts for closing the space in the rubber. Figs. 9 and 10 are details of the pulling device for closing up the space in the rubber.

Like parts are represented by similar letters of reference in the several views.

The working parts of my machine are supported on a main frame, which preferably consists of L-shaped bars a, a, preferably of angle iron and tied together by suitable braces ct (L2 ct ct to make a substantial structure. On the vertical parts of these L-shaped braces, near the top, is secured a cross-barb, on which rests a transverse table I), which maybe supported on the L-shaped braces from brackets or in any other suitable manner. Above the table, supported on the vertical parts of these frame-bars, are two rods 0 and 0', attached rigidly at each end by suitable supports and adapted to form Ways or supports for the clamps or jaws d and e,which hold the tire-retaining hands in the process of uniting the same. These clamps or jaws Fig. a is a plan view of the same are arranged in pairs. One pair of jaws is preferably connectedrigidly to the cross-rods. The other pairis adapted to slideon the crossrods, and means are provided for adjusting them to and from the stationary jaws, pref erably by the aid of a screw f, which screws into the base of one pair of jaws and is supported in a suitable bearing-support located on one of the L-shaped frame-pieces between the transverse rods cand c.

Hinged to the upper part of the frame, preferably the cross-bar b, is a vertical support g, which supports the spindle g, on which the wheel to be equipped with the rubber tire is mounted. This spindleis attached to this support preferably by a sliding block g and is adapted to be adjusted up and down on this pivoted support by means of a pin g extending through the block and adapted to be inserted in a series of openings in said support. On one side of the frame is hinged a swiveled box or support h, through which extends a screw h, having a hand-wheel h thereon, and on the end of this screw is a jaw or clamp 7L adapted to engage a retaining band or bands. On the same side of the frame and preferably slightly below this screwthreaded bar is a clampj, adapted under certain conditions to clamp the wheel -rim to hold the same. The jaws cl and e are preferably extended so as to project into the wheel-rim or band-retaining groove, one of the jaws having auxiliary openings, through which the band or hands are adapted to pass in the manner hereinafter described in tightening the tire. Each of the jaws is normally held open by springs e and is adapted to be closed by cams e operated by handles e These cams operate against movable plates 6 which are adjusted by set-screws e to cause the jaws to close to the required amount to engage the different-sized bands.

In the operation of the machine the tire to be placed on the wheel is provided with the necessary band or bands passing through the same, one end of the band or bands being secured in the stationary jaw e. The other end or ends are passed through the movable jaws cl and through the auxiliary openings and are engaged by the clamp on. the end of the tension-screw. This tension-screw preferably has an adjustable stop 72?, and when it is desired to put compression in the rubber this stop is moved to the proper position on the tensionscrew to correspond with the amount of compression to be placedin the tire. The tension device is then drawn up until it comes against this stop, thus compressing the rubher on the bands to the proper degree, the ends of the rubber resting against the outside of the jaws. The wheel is then placed on the spindle and raised until the ends of the jaws enter the channel, where it is fastened by the pin passing through the opening in the support. The tire is now slipped into the channel. The pin is removed, allowing the weight of the wheel to be on the tire. The stop h isthen released and the tension device drawn up until the bands have tightened the rubber in the channel, the wheel being drawn up so that the jaws project into the channel and retain the wires therein. The wires or retaining-bands are clamped in the jaws and then cutoff to the proper length and joined together in any well-known manner, preferably by brazing, soldering, electric welding, or otherwise, the necessary adjustment for securing the bands being accomplished by moving the adjustable pair of jaws back or forth to the proper position for bringing the ends of the bands together while being united.

After the bands are united the jaws'are released and the wheel is dropped down to a suitable position on the support, when the support is swung on its pivotal center until the whecl-felly is engaged by the clamp A pivoted brace j is placed against the spindle or wheel-hub, the opposite end being connected to the frame in such a manner as to firmly brace the same while the space in the rubber is being closed.

It should have been stated that before the tire is fastened down I place under the rubher and between the rubber and the channel flexible wires or bands at stated intervals apart and bind the rubber tire to the wheel at this point, so that the last compression or a sufficient amount of compression to compensate for the drawing up of the rubber comes within this portion of the tire. \/Vhen the tire is properly on the wheel and swung over to the position before described, the jaw h on the tension device is removed and in place thereof there is inserted a bar m, having a series of clamping devices m, which engage the flexible Wires, and by turning the tension device the rubber is drawn along in the channel, so as to close the space in the rubher over the joints in the retainingbands.

The clamping-jaws or band-holding devices are so arranged that they may be used for either one or two retaining-wires, and to accomplish this I provide an intermediate or tongue piece e having a slotted opening adapted to fit over the connecting-bar c of the jaws. By removing the pivot-pin of one of the jaws of the pair and slipping the tonguepiece between the said jaws and over the connecting-bar then it may be used for two retaining-bands, the bands being clamped on opposite sides of the tongue-piece. To accomplish this, I preferably provide the connecting-bar with two or more holes 6" e to which the pivoted jaw is attached to compensate for the different distances between the jaws in operation, the adjustable opposing part for the clamp being adapted to adjust the throw of the jaw to compensate for the changed position of the jaws or different thicknesses of the wires or hands used.

For matter shown and described but not claimed in this specification reference maybe had to my pending applications, Serial Nos. 718,456 and 718,457, filed May 26, 1899.

Having thus described my invention, I claim- I. In a rubber-tire machine, clam ping-jaws mounted on transverse rods in a vertical main frame such as described, means for varying the distance between said jaws, a vertical wheel-support pivoted to a cross-bar or table in'said frame below said rods and adjacent to said jaws and a tension device adjacent to said jaws, substantially as and for the purpose specified.

2. The combination, in a rubber-tire machine, with the band-holding devices, and means for adjusting the same, a tension device arranged adjacent thereto, said tension device being swivelly mounted as described, a wheel-clamp adjacent to said tension device, and a pivoted wheel-support adapted to be swung to different positions so that said swiveled tension device may be operated to tighten the bands and close the space in the rubber, substantially as specified.

3. The combination with the upright frame consisting of the vertical bars and a cross-bar and table as described, a wheetsupport pivoted to said cross-bar, a wheel-clamp on said frame, and a pivoted brace for bracing said wheel-support when the wheel is in engagement with said wheel-clamp, substantially as specified.

4. In a rubber-tire machine, band-holding jaws pivoted together a connecting-bar on which their pivot is adjusted, a detachable tongue arranged between said jaws and held in position by said connecting-bar, a bowspring to hold said jaws normally open and a cam and an adjustable hinged cam-face, for opening and closing said jaws with or without said tongue, substantially as and for the purpose specified.

In testimony whereof I have hereunto set my hand this 6th day of May, A. D. 1899.

SAMUEL W. COLLINS.
